Feature
Proforma invoices
A proforma invoice tells a buyer exactly what the final bill will look like, before the sale is made. It is how many businesses ask for an advance. Cashflow OS makes proforma invoices with your logo, colours, letterhead, signature and bank and UPI details, and shares them as a PDF on WhatsApp or email.
- Ask for the advance in writing
- Your logo, bank and UPI
- PDF on WhatsApp or email
- From your Tally items

The problems proforma invoices solves
What goes wrong without it, and what changes with Cashflow OS.
- The problemAdvance asked for on a phone call
The buyer's accounts office will not pay without a document.
With Cashflow OSA branded proforma with the advance statedShow goods, rates, GST and the advance asked, on your letterhead, as a PDF.
- The problemBuyer calls back for your bank details
Every payment waits for someone to send the account number again.
With Cashflow OSBank and UPI details printed on the documentThe buyer pays the advance straight from the proforma, without asking you.
- The problemProforma typed in Word, different every time
Staff use old files, wrong rates and missing GSTINs.
With Cashflow OSSame items, parties and branding as everything elseItems and parties come from your Tally books; logo, letterhead and signature are set once.
- The problemPrice still changing, but a proforma went out
Two different numbers in the buyer's inbox cause confusion.
With Cashflow OSQuotation first, proforma once terms are agreedNegotiate with a quotation, then send the proforma that matches the final bill.
Quotations - The problemFinal invoice retyped from the proforma
Lines get missed and the tax invoice differs from what was agreed.
With Cashflow OSConvert into a Tally sales invoiceOnce writing is on, the proforma converts into a Tally sales order or invoice with the same lines.
Sales orders to Tally - The problemAdvance received but not in the books

What it does
What you can do with proforma invoices
A proforma that looks like the final bill
How it works. Pick the customer and add items from your Tally items with quantities and rates. GST is worked out from the item and the party's state, and the document carries your logo, colours, letterhead and signature.
- Clearly labelled proforma, not a tax invoice
- Own numbering series, separate from invoices
- Validity and advance stated in the terms
In practiceA solar dealer quotes a school ₹3,40,000 before GST for inverters and batteries and asks for 50%, ₹1,70,000, on the proforma.

Bank and UPI details for the advance
How it works. Your bank and UPI details print on every proforma, so the buyer can pay the advance straight from the document.
- No call needed to ask for account numbers
- Advance arrives sooner while the buyer is keen
- Same details on quotations and other documents
In practiceSunrise Public School's accounts office approves the proforma on Tuesday and transfers ₹1,70,000 by NEFT using the details on it.

Shared on WhatsApp or email
How it works. Share the proforma as a PDF on WhatsApp or by email, from the phone app or the web app, so it lands in the same thread as the enquiry.
- Sent from the buyer's office, the site or the road
- Buyer forwards it to their accounts team easily
- Saved alongside your other documents
In practiceThe salesman shares the PDF with the school's principal on WhatsApp, who forwards it to the trust's accountant the same day.

Advance recorded, then the invoice
How it works. When the advance arrives, record the receipt against the party (from the app, if writing is switched on), then convert the proforma into a Tally sales invoice when you supply.
- Party ledger shows the advance the same day
- Tax invoice carries the same lines as agreed
- Tally validates each entry
In practiceThe school's ledger shows the ₹1,70,000 advance on Wednesday; after dispatch, the invoice goes into Tally and the balance is due on delivery.

Guide
Proforma invoices: the full guide
How it works day to day, who does what, and the points to watch.
What a proforma invoice is for
A proforma invoice is a document sent before supply. It shows the goods or services, quantities, rates, taxes and total, much like a tax invoice, but it is not a tax invoice and does not create a GST liability by itself. Businesses use it to:
- request an advance payment before dispatch;
- help a buyer raise a purchase order or get internal approval;
- support a loan, subsidy or import process that needs a formal price document;
- confirm the final commercial terms before the sale.
Our guide on proforma invoice vs tax invoice explains the difference in detail, and the glossary entry on proforma invoice gives the short version. GST treatment of advances depends on the type of supply; see GST on advances received. This is general information, not tax advice.
How it works in Cashflow OS
Proforma invoices are part of the documents module, alongside quotations, purchase orders and delivery challans. They use the same items and parties as your Tally books, and the same branding you set once: logo, colours, letterhead, signature, and bank and UPI details. Share each one as a PDF on WhatsApp or by email, from the phone or the web app.
Because the bank and UPI details are printed on the document, a buyer can pay the advance straight from it, without calling you for account numbers.
A worked example: advance before dispatch
A solar equipment dealer receives an order from a school for inverters and batteries worth ₹3,40,000 before GST. The dealer's terms are 50% advance for institutional orders. He sends a proforma invoice:
| Line | Amount |
|---|---|
| Goods, before GST | ₹3,40,000 |
| GST (as per item rates) | shown line by line |
| Advance requested, 50% of goods value | ₹1,70,000 |
| Payment | Bank transfer or UPI, details on the document |
The school's accounts office uses the proforma to approve payment and transfers the advance. When the advance is received, the dealer records the receipt in Tally (from the app, if writing is switched on), dispatches, and raises the tax invoice in the usual way. GST rates for each item should be checked on the GST portal; the example leaves them out deliberately.
Quotation, proforma, invoice: using each at the right time
Businesses often send the wrong document at the wrong stage, which confuses buyers and sometimes their accountants. A simple sequence works for most B2B sales:
- Quotation while the buyer is still comparing and negotiating. It can change.
- Proforma invoice once price and terms are agreed and you need an advance or the buyer needs a formal document for approval. It should match what the final bill will be.
- Tax invoice in Tally when the goods or services are supplied. This is the document that counts for GST.
- Delivery challan if goods move before or without an invoice, for example on approval or for job work.
Cashflow OS covers the first, second and fourth as branded documents, and the tax invoice stays in Tally. Keeping the stages distinct also helps when a buyer's auditor asks why there are two documents with similar amounts: one is clearly marked proforma, the other is the tax invoice, and their numbers come from different series.
Who uses it
- Dealers and distributors who supply institutions or new customers against advance.
- Manufacturers taking made-to-order work.
- Exporters and project suppliers whose buyers need a formal price document.
- Service businesses asking for part payment before starting a job.
Tips
- Label it clearly as a proforma invoice, so nobody mistakes it for a tax invoice.
- Number proformas in their own series, separate from tax invoices; see invoice numbering rules.
- State validity and the advance amount in the terms.
- Record advances in Tally against the party the day they arrive, so outstanding stays right.
- Use a quotation first if the price is still being negotiated; send the proforma once terms are agreed.
What it does not do
- A proforma invoice is a document, not an entry in Tally's books; it does not affect stock, accounts or GST returns.
- It does not collect payment; the buyer pays you directly using the bank or UPI details on it.
- It does not replace the tax invoice, which is raised in Tally when the supply is made.
